1850-O $10 AU55 NGC. The 1850-O is seldom seen with only
150-175 pieces estimated in all grades, but it is more notable as a
condition rarity with at most two dozen pieces known in AU. This
Choice example has exceptionally bright surfaces, in part due to
the partially reflective finish found in the fields of most 1850-O
tens. The strike details are above-average for the issue and there
are none of the usually seen heavy abrasions this issue is so
well-known for. Census: 22 in 55, 15 finer (5/11).(Registry
values: N2998) (NGC ID# 2639, PCGS# 8605)
